[0001] TITLE OF INVENTION:

[0002] A SYSTEM FOR OPERATING ONE OR MORE LIGHTS OF A VEHICLE AND METHOD THEREOF

[0003] FIELD OF THE INVENTION

[0004]

[0001] The present invention generally relates to a lighting system of a vehicle, more particularly, relates to a system for operating one or more lights for a vehicle.

[0005] BACKGROUND OF THE INVENTION

[0006]

[0002] In the existing vehicles, advanced lighting system includes adaptive or dynamic intensity features. The adaptive or dynamic intensity features of the lighting system relies heavily on communication modules such as Controller Area Network (CAN), Local Interconnect Network (LIN), or even Ethernet. These features are enabled by controlling the intensity or pattern of the output beam via a microcontroller. Given the complex architecture of the lighting system with adaptive or dynamic intensity features, there is a potential risk of communication failure or microcontroller damage due to adverse conditions, prolonged use, or aging over several years. Such failures can result in malfunctioning of high beam or low beam lights of the vehicle. It can even lead to shutdown of complete lighting system, leading to replacement costs for the customer before the warranty period ends and thus causing dissatisfaction of customer.

[0007]

[0003] Further, different throw of light may be needed for different speeds to navigate different terrains. Furthermore, dependency on only a single microcontroller to control the lighting system of the vehicle will put us on the risk of failure of lighting system in the vehicle. In order to eliminate the above existing problem and to improve reliability of the lighting system of the vehicle, redundancy can be increased, but that comes with additional cost and space requirements.

[0008]

[0004] Typically, in the existing vehicles, for an example, in a traditional headlamp, high beam operates at constant intensity which is sometimes not sufficient at high speeds or sometimes it is overpowering at low speeds.

[0029] DETAILED DESCRIPTION OF THE INVENTION

[0030]

[0019] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder.

[0031]

[0020] The present invention generally relates to a lighting system and particularly relates to a system for operating one or more lights for a vehicle. In the ensuing exemplary embodiments, the vehicle 10 is a motorcycle. However, it is contemplated that the disclosure in the present invention may be applied to any automobile like a scooter, any other saddle type vehicle and any other automobile which is capable of accommodating the present subject matter without defeating the scope of the present invention.

[0032]

[0021] In an embodiment, the vehicle may be a two-wheeled vehicle, a three- wheeled vehicle, a four-wheeled vehicle, or a multi-wheeled vehicle. The vehicle may be powered by an internal combustion engine or an electric motor through one or more batteries or a hybrid-electric motor as per requirement. It should be understood that the scope of present invention is not limited to the illustrated two-wheeled vehicle having the internal combustion engine.

[0033]

[0022] Figure 1 illustrates a left side view of an exemplary vehicle 10, in accordance with an embodiment of the present invention. The vehicle 10 comprises a front wheel 12, a rear wheel 14, a frame structure (not shown) and a rider seat 16. The frame structure includes a head pipe (not shown), a main tube (not shown), a down tube (not shown), and a pair of seat rails (not shown). A headlamp 18 and an instrument cluster (not shown) are arranged on an upper portion of the head pipe. Further, the head pipe supports a steering shaft (not shown) disposed inside the head pipe. A front suspension (22) coupled to the steering shaft (not shown) is provided at a front of the vehicle 10, and the front wheel 12 is supported by the front suspension. An upper portion of the front wheel 12 is covered by a front fender 20 mounted to a lower portion of the front suspension 22. A handlebar 24 is operatively coupled to the steering shaft and can rotate about the head pipe for steering the vehicle 10.

[0034]

[0023] The vehicle 10 may be powered by an internal combustion engine (not shown) or an electric motor (not shown) through one or more batteries or a hybrid-electric motor as per requirement. The vehicle 10 includes a prime mover (not shown) that is adapted to provide motive force for movement of the vehicle 10. In an embodiment, the prime mover can be the electric motor (not shown). In an embodiment, the prime mover can be the internal combustion engine. A swingarm (not shown) is connected to the frame structure to swing vertically, and the rear wheel 14 is connected to a rear end (not shown) of the swingarm. The swingarm is coupled to the vehicle 10 by a rear suspension (not shown) at a position rearwardly of a pivot point of the swingarm on the frame structure of the vehicle 10. A grab rail 28 is also provided to the seat rails at a rear of the rider seat 16. The rear wheel 14 arranged below the rider seat 16 rotates by the motive force generated by the prime mover. A rear fender 30 is disposed above the rear wheel 14. A taillight 26 is disposed at a rear of the rider seat 16. In an embodiment, the vehicle 10 includes one or more lights 102 which includes the headlamp 18 and the taillight 26.

[0035]

[0024] Figure 2 illustrates a system 100 for operating the one or more lights 102 of the vehicle 10. The system 100 includes at least one sensor 101 on the vehicle 10 to generate vehicle speed data. In an embodiment, the sensor 101 is a vehicle speed sensor which generates vehicle speed data. The system 100 further includes a control unit 103. The control unit 103 is disposed on the vehicle 10. The control unit 103 is communicatively coupled to the at least one sensor 101 and one or more drive units 104 of the one or more lights 102. In an embodiment, the drive units 104 are configured to drive the one or more lights 102. In another non-limiting embodiment, the one or more lights 102 is the headlight 18 and / or the taillight 26. The control unit 103 is configured to receive the vehicle speed data from the sensor 101. The control unit 103 is configured to drive the one or more drive units 104 to change an intensity of light emitting from the one or more lights 102 based on the vehicle speed data received from the sensor 101 and one or more predefined conditions. The one or more predefined conditions are availability of the control unit 103 and availability of communication bus.

[0036]

[0025] The one or more drive units 104 which are driven by the control unit 103 perform change in the intensity of light emitting from the one or more lights 102 based on the change in the speed data of the vehicle 10. When the control unit 103 is available, the control unit 103 is configured to determine the change in the speed data of the vehicle 10. The control unit 103 is said to be "available", when the control unit 103 is electrically connected to one or more components of the vehicle 10. In a nonlimiting example, the control unit 103 is said to be available, when the control unit 103 is electrically connected to at least one or more sensor 104 and the one or more lights 102. The change in the speed data of the vehicle 10 is used by the control unit 103 to perform change in the intensity of light emitting from the one or more lights 102. In an embodiment, the control unit 103 has pre-coded data which will govern the required change in the intensity of light emitting from the one or more lights 102 as per change in speed data of the vehicle 10. In some embodiments, the pre-coded data is a data repository having details of the required light intensity basis the speed of the vehicle 10. In a non-limiting example, when the speed of the vehicle 10 is 20 kmph, the intensity of light is set at 10%. When the speed of the vehicle 10 is 50 kmph, the intensity of light is at 30%. When the speed of the vehicle 10 is 70 kmph, the intensity of light is at 50%. When the speed of the vehicle 10 is 120 kmph, the intensity of light is at 100%.

[0026] As shown in Figure 3A, the communication bus includes a Controller Area Network (CAN) transceiver 114 which receives CAN high 108a and CAN low 108b signals. The CAN transceiver 114 receives and transmits information acquired from one component of the vehicle 10 to another component of the vehicle 10. In a nonlimiting example, the CAN transceiver 114 acquires speed of the vehicle 10 from the one or more speed sensor 101 on the vehicle 10 by using the CAN high 108a and the CAN low 108b signals. Further, the CAN transceiver 114 transmits the speed data of the vehicle 10 to the control unit 103. The control unit 103 is configured to drive the one or more drive units 104 (drive unit 1, drive unit 2) to change an intensity of light emitting from the one or more lights 102 based on the vehicle speed data received from the sensor 101 and one or more predefined conditions. In an embodiment, the control unit 103 is configured to drive the one or more drive units 104 to increase the intensity of light emitting from the one or more lights 102 based on the vehicle speed data received from the sensor 101 and the one or more predefined conditions. In an alternate embodiment, the control unit 103 is configured to drive the one or more drive units 104 to or decrease the intensity of light emitting from the one or more lights 102 based on the vehicle speed data received from the sensor 101 and the one or more predefined conditions. In another alternate embodiment, the control unit 103 is configured to drive the one or more drive units 104 to increase and decrease the intensity of light emitting from the one or more lights 102 based on the vehicle speed data received from the sensor 101 and the one or more predefined conditions.

[0037]

[0027] Further, as shown in figure 3B, when at least one of the communication bus is unavailable and the control unit 103 is unavailable, the one or more drive units 104 is driven by at least one of a High Beam Actuation Logic unit 126 and a power supply 112 to maintain a constant intensity of light emitting from the one or more lights 102 irrespective of change in the speed data of the vehicle 10. In an embodiment, when at least one of the communication bus is unavailable and the control unit 103 is unavailable, the power supply 112 provides a voltage through protection circuit 116 to the drive unit 102 (drive unit 2) to maintain the constant intensity of light emitting from the one or more lights 102 (LED Mesh 2 / Low Beam). In another embodiment, when at least one of the communication bus is unavailable and the control unit 103 is unavailable, the High Beam Actuation Logic unit 126 maintain the constant intensity of light emitting from the one or more lights 102 (LED Mesh 1 / High Beam). The control unit 103 is said to be “unavailable” due to at least one of a hardware fault in the control unit 103 and power supply failure to the control unit 103. In an embodiment, the communication bus is said to be “unavailable” due to at least one of poor wiring of communication bus and malfunction of the sensor 101 connected to the communication bus. In an embodiment, when the control unit 103 or the CAN transceiver 114 fails i.e., the control unit 103 or the communication bus fails, the intensity variation of one or more lights 102 may be lost. However, the one or more lights 102 emits the constant intensity of light because of the connection that bypasses or overrides the control unit 103 i.e., the connection of the drive units 104 (drive unit 1 and drive unit 2) with the high beam actuation logic unit 126 and the power supply 112.

[0038]

[0028] Eurther, as shown in figure 3A, in an embodiment, an active switching element (denoted by ‘A’ in figure 3 A) is connected in series with the power supply 112 and the one or more lights 102. The active switching element may include, but not limited to, a transistor. The active switching element is configured to regulate flow of a driving current from the power supply 112 to the one or more lights 102 and the control unit 103. Eurther, the control unit 103 is electrically connected to a protection circuit 116, the CAN transceiver 114, and a Low Dropout Regulator (LDO) 118. The LDO 118 controls the driving current supplied from the power supply 112 to the various components of the vehicle 10. In an embodiment, the LDO 118 may provide current to the CAN transceiver 114 and the control unit 103. The LDO 118 is used to maintain the input voltage / driving voltage supplied to the CAN transceiver 114 and the control unit 103 which are stable over time, over load variations and over changes in ambient temperature. The LDO 118 is supplied with voltage from Common Mode Differential Filters 120.

[0039]

[0029] In an embodiment, the protection circuit 116 includes at least one of common mode and differential filters 120, Electronic Shut-Off (ESO) circuits, and transient and reverse protection circuits. The transient and reverse protection circuits, such as a reverse protection diode is used to protect the circuitry from reverse voltage, a transient voltage protection diode (e.g. Zener Diode) is used to protect the circuitry from transient voltage, and a reverse protection capacitor is used for filtering of input power received from the power terminal of the power source. The protection circuit 116 includes the common mode differential filters 120 for filtering out a common mode differential voltage. The Electronic Shut-Off (ESO) circuits is used to safely disconnect electrical power from the circuitry in emergency situations. The High Beam (HB) switch TP 122 present on the handlebar 24 (shown in figure 1) is configured to switch ON a high beam (LED Mesh 1, as shown in figure 3 A) from the one or more lights 102. Further, an LED binning circuit 128 is electrically connected between the drive unit 1 and drive unit 2 of the one or more lights 102. The LED binning circuit 128 is used to sort LEDs according to various quality criteria such as color, voltage, and brightness. LEDs are usually divided into bins based on their performance at a specified operating condition. This approach improves the consistency of the LED performance. A thermal derating circuit 130 is connected to the control unit 103 and the drive unit 104 of the one or more lights 102. The thermal derating circuit 130 keeps the LED mesh of the one or more lights 102 working within its safe power dissipation limits. When temperature of the LED mesh of one or more lights 102 exceeds a predefined limit, the current in the LED mesh is reduced and the LED mesh is dimmed to protect it from overheating.

[0040]

[0030] Figure 4 is a flow diagram of a method 300 depicting operation of the one or more lights 102 of the vehicle 10, in accordance with an exemplary embodiment of the present invention.

[0031] At a step 402, at least one sensor 101 generates the vehicle speed data. In an embodiment, the sensor 101 is a vehicle speed sensor which generates the vehicle speed data. The control unit 103 is communicatively coupled to the at least one sensor 101 and one or more drive units 104 of the one or more lights 102. At a step 404, the control unit 103 receives the vehicle speed data from the at least one sensor 101. At a step 406, the control unit 103 drives the one or more drive units 104 to change the intensity of light emitting from the one or more lights 102 based on the vehicle speed data received from the sensor 101 and one or more predefined conditions. The control unit 103 drives the one or more drive units 104 by sending a signal to the one or more drive units 104 to change the intensity of light emitting from the one or more lights 102. The one or more predefined conditions are availability of the control unit 103 and availability of communication bus. The one or more drive units 104 which are driven by the control unit 103 perform change in the intensity of light emitting from the one or more lights 102 based on the change in the speed data of the vehicle 10. When the control unit 103 is available, the control unit 103 is configured to determine the change in the speed data of the vehicle 10. The change in the speed data of the vehicle 10 is used by the control unit 103 to perform change in the intensity of light emitting from the one or more lights 102. Further, when at least one of the communication bus is unavailable and the control unit 103 is unavailable, the one or more drive units 104 is driven by at least one of the High Beam Actuation Logic unit 126 and the power supply 112 to maintain the constant intensity of light emitting from the one or more lights 102 irrespective of change in the speed data of the vehicle 10. The unavailability of the control unit 103 is due to at least one of the hardware fault in the control unit 103 and power supply failure to the control unit 103. The unavailability of communication bus is due to at least one of poor wiring of communication bus and malfunction of the sensor 101 connected to the communication bus.

[0032] In an embodiment, the active switching element (denoted by ‘A’ in figure 3 A) is connected in series with the power supply 112 and the one or more lights 102. The active switching element includes the transistor. The active switching element is configured to regulate flow of a driving current from the power supply 112 to the one or more lights 102 and the control unit 103. Further, the control unit 103 is electrically connected to the protection circuit 116, the CAN transceiver 114 and the Low Dropout Regulator (LDO) 118.

[0041]

[0033] Advantageously, the present invention provides a speed dependent intensity- controlled lights for better visibility and for better battery management. The present invention enables variation of intensity of the high beam and the low beam based on speed of the vehicle. Further, the present invention ensures that even when the control unit or the communication bus fails, the lights should behave as traditional lights which emits a constant intensity of light, meeting the homologation requirement. In case, the control unit or the CAN transceiver fail, the intensity variation of one or more lights may be lost, but the one or more lights function at a constant intensity because of the connection that bypasses or overrides the control unit 103 i.e., the connection of the drive units with the High Beam Actuation Logic unit and the power supply.

[0042]

[0034] The present invention improves the reliability of lighting system of the vehicle. Further, the present invention reduces the discomfort of customers while riding the vehicle. Furthermore, the present invention reduces the replacement costs of replacing the complete lighting system in case of malfunctioning of high beam or low beam lights of the vehicle.

[0043]

[0035] The present invention enables different throw of light as needed for different speeds to navigate different terrains. Furthermore, due to present invention, the dependency on a single control unit for operating the one or more lights is reduced and hence, the redundancy has increased without increasing the additional cost and space requirements.
